Given numbers are 721,123,760,820,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,123,760,820,804 is 4515738360.
Find LCM of 721,123,760,820,804 with Prime Factorization
2 | 721, 123, 760, 820, 804 |
2 | 721, 123, 380, 410, 402 |
3 | 721, 123, 190, 205, 201 |
5 | 721, 41, 190, 205, 67 |
41 | 721, 41, 38, 41, 67 |
721, 1, 38, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 41 x 721 x 1 x 38 x 1 x 67 = 4515738360
Therefore, the lowest common multiple of 721,123,760,820,804 is 4515738360.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
721 x 123 x 760 x 820 x 804 = 44434865462400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
721 : 1, 7, 103, 721
123 : 1, 3, 41, 123
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,123,760,820,804, is 1.
Now, the common factors can be found like this.
721:7x 103
123:3x 41
760:2x 2x 2x 5x 19
820:2x 2x 5x 41
804:2x 2x 3x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 5x 41 = 9840
Therefore, the value for common factors is 9840.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 44434865462400/(1x9840)
LCM = 44434865462400/9840
LCM = 4515738360
Thus, we can understand that the LCM of 721,123,760,820,804 is 4515738360.
